(If you don't know what Twitter is, please check out this post: Getting started with Twitter)
I have seen several lists of educators on Twitter, like this one and recently I discovered this wiki which organizes us by subject area. It inspired me to create a list that could be sorted across different criteria like country, state, subject or grade level. In an attempt to create a more malleable list I made a Google form for educators to fill out. I then made the corresponding spreadsheet public, so that anyone can sort it. If you haven't already, please complete the form and add yourself to the list.
I took the data that we have collected so far and used Many Eyes to create a treemap of the results. If you click on the image below you can see the results so far.
